This circuit approach provides a simple way to control multiple LEDs from a processor. Doing so enables the solutions to LED aging and variability to be implemented in a more cost-effective manner.

Frank Hertel’s project: three individually dimmable LED lights. (Frank is the master of recycling; the wooden mounting pedestals are the panels from a decommissioned ATI console!) Thanks for your ...

Sponsored by Texas Instruments: The LED is the dominant lighting solution today, but the processes involved in driving and dimming them are more sophisticated than you perhaps thought. Light-emitting ...
